Proper air filter: Parts

A good air filter does what it was designed to do. The only reason this isn't 5 stars is because the lid keeps coming off. Use screw lock and buy extra black screws from hardware store.

Pros
  • understandable even for the old ones
Cons
  • Slightly cracked

looks good, but it's the loudest breather I've ever heard.

It works, looks good but it's the loudest breather I've ever heard, you can hear the valves sucking air with every beat, especially on non-original cams. Aggravating

Pros
  • New
Cons
  • Not sure

Looks great and easy to fit

Looks great on bike, easy to fit. The only thing I want is that it doesn't get damaged when I get it. However, I like my solution to hide the error. It was a packaging issue but I'm still very disappointed with it. As for the theme, I like it a lot. I'm still working on the exhaust so haven't ridden it a few miles yet, but it looks killer.

Pros
  • Well made
Cons
  • No
